The Ministry of Ecology and Environment released the results of the national air quality forecast meeting in the second half of April
China Environmental Monitoring Station and the Central Meteorological Observatory and the National Meteorological Observatory, National Air Pollution Prevention Customs Customs Center, etc., will carry out the National Air Quality Forecast Association from April 16th to April 30th from April 16th to April 30th.
In the second half of April, the northeast, South China and Southwest region were dominated by excellence.Mild pollution or short -term moderate pollution may occur in the southern part of Hebei, the central part of the Yangtze River Delta, and northern Ningxia.Due to the rise in temperature in the middle and late period, PM2.5 and ozone compound pollution may occur in Beijing -Tianjin -Hebei and the surrounding areas and southwestern regions.Affected by sand and dust weather, medium to severe pollution may occur in the northern and eastern cities of Xinjiang, and southern Xinjiang is mainly due to medium to severe pollution, and severe pollution may occur in some periods.
Beijing -Tianjin -Hebei and surrounding areas: In the second half of April, the overall diffusion conditions in the early stage were average. In the mid -term, it was affected by cold air in Northwest China. In the later period, due to the rise in temperature, oxygen mild pollution may occur.
Beijing: In the second half of April, the overall diffusion conditions in the early stage were favorable, and the diffusion conditions in the middle and late stages of the late term gradually changed.On the 16th, due to the effects of high pressure and northwind, the diffusion conditions are favorable, and the air quality is expected to be good. On the 17th, in the high -pressure intermittent period, due to the influence of southwind, the middle layer temperature has risen.In some periods, it may occur to mild pollution.On the 18th to 24th, the cold air effect is more frequent, the northwind is the main, the diffusion conditions are favorable, and the air quality is mainly good.Ozone composite pollution.The primary pollutants are mainly PM2.5 and ozone.
The Yangtze River Delta area: In the second half of April, the southern part of the area is mainly good, and the central and northern parts are mainly mild pollution.
Fenwei Plain: In the second half of April, most of the regions were affected by the precipitation process from 18-20, 26-28, and the conditions of wet removal were favorable; on the 22-23, they were affected by the transmission of upstream sand and dust, and the short -term sand and dust weather may occur;During the rest of the time, the diffusion conditions are generally, and most of the air quality in the area is mainly based on good to mild pollution.
Northeast region: In the second half of April, cold air activities are more frequent, and the overall diffusion conditions in the area are better. It is expected that most of the air quality in the area is mainly excellent, and mild pollution may occur in local area.
South China Region: In the second half of April, the overall atmospheric diffusion and wet removal conditions of the region were good, and the air quality was mainly excellent. Among them, on the 16th to 17th, the central and northern and east of Guangdong were gently polluting.The primary pollutants are mainly ozone or PM2.5.
Southwest region: In the second half of April, most of the overall diffusion conditions in the southwest region were average.
Northwest region: In the second half of April, most of the region was affected by multiple rounds of cold air. The overall diffusion conditions were good, the air quality was mainly good, and mild pollution may occur in the local area.
